Update .NET extension reload E2E contract

[dmytrostruk]

Summary

• update the loaded-extension E2E contract for session.extensions.reload
• verify reload re-reads persisted global settings and clears a session-local disable when the global default remains enabled
• assert the relaunched extension is running with a PID

Depends on github/copilot-agent-runtime#13831. The current SDK CI runtime still implements the previous session-local reload behavior, so this contract test becomes green when that runtime change is available.

Validation

• git diff --check
• .NET test execution unavailable locally because this environment has no dotnet toolchain

Cross-SDK Consistency Review ✅

This PR modifies only one .NET E2E test file (dotnet/test/E2E/RpcExtensionsLoadedE2ETests.cs), updating Reload_Preserves_Disabled_State_Across_Calls → Reload_Restores_Globally_Enabled_State to reflect the correct contract for Extensions.ReloadAsync().

No cross-SDK consistency issues found. Specifically:

• No public SDK API surface was changed — this is a test-only fix
• The corrected behavior (reload re-reads global settings and clears session-local disabled state) is an internal server contract, not a cross-language API shape
• No equivalent "reload preserves disabled state" E2E test exists in other SDKs (Node.js, Python, Go, Java, Rust) that would need updating

The changes maintain cross-SDK consistency.

Closing for sequencing: this contract-test update should be generated and applied with the SDK release after github/copilot-agent-runtime#13831 is finalized, rather than landing as a standalone SDK PR now.
